At the termination of this forward feeding movement the parts oeeupy the position shown in I`ig. 2, the flap of the envelop being bent at a substantial angle to the body thereof and the thickened portion i' of the presser-plate l pressing the gnmmed portion of said flap against the pad a to thereby moisten the same for wading.
